Based on that device name, I'm assuming you're using wifi. I'm also
assuming you're using DHCP to get an IP address for your machine and
that the DHCP server is your wireless access point/router/whatever.

Not surprising. On the vast majority of networks, the first usable IP
(in your case 192.168.1.1) is the gateway and should be pingable. Some
networks use the LAST usable IP as the gateway (nowhere near as
common) and still others use some arbitrary address as the gateway
(pretty rare).
What disturbs me is that your DHCP server didn't offer any external DNS
servers and that, based on the fact it only gave you its own address,
that it's not acting as either a caching DNS server or proxying your
requests through.

That data may be cached by your browser if you examined it after
adding the 8.8.8.8 nameserver to your /etc/resolv.conf. Try a reboot
or flush the browser's cache and try to fetch the metadata again via
the browser without the 8.8.8.8 nameserver in /etc/resolv.conf. I'll
bet it fails.

It still looks like a network issue to me in that the DNS services
aren't happening. Check your NetworkManager (NM) config for that device,
go to the "IPv4 Settings" tab (assuming you're using IPv4) and make
sure that if you're using DHCP, you have "Automatic (DHCP)" selected in
the "Method" section and NOT "Automatic (DHCP) addresses only" and that
you don't have anything in the "Additional DNS servers" section, then
restart Network Manager:
sudo systemctl restart NetworkManager
Recheck the /etc/resolv.conf file to see if you have any additional
nameservers defined. If not, then you COULD add 8.8.8.8 to the
"Additional DNS servers" section of the NM config and do another
NM restart. The thing that bothers me is that the DHCP stuff is not
giving you any nameservers to use other than the router and that the
machine it is giving you (192.168.1.1) isn't acting like a resolver
itself and it should if it doesn't pass along any nameservers.
The vast majority of wireless routers pass through the DNS servers they
get from their ISP upstream providers. The WAN side of your wireless
router gets its IP via DHCP from your ISP along with nameservers to
use. It usually passes those nameservers along to ITS DHCP clients on
the LAN side of things. If not, they run a caching name server or proxy
that the LAN DHCP clients use.
